angularjs ng-repeat asynchronous JavaScript

I'm prototyping a solution and Does anyone know how to I've tried everything I can think of but I'm working on a project and hit a roadblock... I'm working with a frustrating scenario with AngularJS 1.8 where my `ng-repeat` is not rendering the updated data correctly when fetching it asynchronously. I have a service that retrieves a list of items from a REST API, but after the data is loaded, I can occasionally see stale data being displayed instead of the latest items. Here's a simplified version of my setup: ```javascript angular.module('myApp', []) .service('DataService', function($http) { this.getItems = function() { return $http.get('https://api.example.com/items'); }; }) .controller('MainCtrl', function($scope, DataService) { $scope.items = []; $scope.loadItems = function() { DataService.getItems().then(function(response) { $scope.items = response.data; }); }; }); ``` In my HTML, I use `ng-repeat` like this: ```html <div ng-controller="MainCtrl"> <button ng-click="loadItems()">Load Items</button> <ul> <li ng-repeat="item in items">{{ item.name }}</li> </ul> </div> ``` I've tried ensuring that the `$scope.items` is set only after the data has been fully loaded. However, when I click the button to load the items, sometimes the old list of items remains displayed for a moment before updating, or even worse, it shows a mix of old and new items. I also checked for any potential issues with caching in the browser and made sure to disable it in my API calls. To troubleshoot, I added some console logs in the `then` function to confirm that the new data is being fetched correctly: ```javascript DataService.getItems().then(function(response) { console.log('Fetched items:', response.data); $scope.items = response.data; }); ``` The log shows the correct data every time, but the display is inconsistent. Are there any best practices for handling asynchronous data updates in AngularJS that could guide to ensure that `ng-repeat` reflects the most current data immediately? I'm working on a service that needs to handle this. What's the best practice here? For context: I'm using Javascript on Windows 10. How would you solve this? This is my first time working with Javascript LTS. This is happening in both development and production on Debian. Is there a better approach?
